If you're familiar with Blockstack, they have monthly app mining contest where each dapp will be ranked (scored by multiple methods) and paid from $20,000 to a couple of cents per app. Pretty nice deal right?
It is true that Dcasso (https://dcasso.app/) has been ranked top 30 and earning over $5,500 every month since November 2019, by being a doodling game.
BUT, is Dcasso JUST a doodling game? Let's take a deeper look into what it is.

From the app description, I got

"Dcasso is a fun and judgement-free drawing platform.
• It's not about drawing the best sketch, because there are many tools out there to serve that purpose.
• Dcasso is a game where you're given a random prompt and a set time, you're tested on how fast and creative you can come up with a drawing."

So yes Dcasso IS a doodling game, but with a twist. Taking a look at hundreds of sketches on Dcasso, I actually ended up laughing at many of them. Due to the time constraint, most sketches ended up being creative, or "creative". Although Dcasso might not be privacy-focused, it does bring an entertainment value to Blockchain and Blockstack community. Dcasso seems to be one of those apps that actually bring non-crypto users to the Blockchain community because of the value Dcasso offers. I'm new to decentralization. For utility apps, I found it harder to switch from centralized apps like Google Docs to Blockstack suite app due to my habits, but I don't find it hard to try out and keep coming back to decentralized games.

After all, maybe it's worth taking a shot at https://dcasso.app/?
